IMPROVEMENT IN SNAPV-HOOKS.

Specification forming part of Letters Patent No. 175,9 l2. dated April11, 1876; application lcd December 21, 1875.

To all whom it may concern Beit known that I, CHARLES. W. BLAKEs- LEE,of Litchfield, in the county of Litchfield and State of Connecticut,have invented a certain new and useful Improvement in Snap- Hooks; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled' in theart to which it appertains to make and use it, reference being had tothe accompanying drawing, which forms a part of this specication.

In the drawing, Figure l is a perspective view of the hook. Fig. 2 is aview of the inside of the enlarged forward end of the body, and ofenlarged forward end of the tongue, in contact with the enlarged end ofthe body of the hook. Fig. 3 is a View of the inside of the enlarged endof the body. Fig. 4 is a view of the enlarged end and side ofthe tonguewhich comes against theenlarged end of the body of the hook.

My invention relates to snap or rein hooks, and its object is to obtaingreater security against their accidental unhooking. The inventionconsists in making an enlargement on the forward ends of both the bodyand tongue of the hook, in a manner hereinafter more fully set forth andclaimed.

Fig. l is a view of all the parts of the hook. A is the body of thehook, the forward end of which terminates in an enlargement or shield,a, and a rib, a', formed on the inside of the shield a, as shown in Fig.2, and also in Fig.

3. The body A of the hook does not diler except in the form of itsforward end from the bodies of ordinary hooks, and is furnished with aspring, operating on the tongue in the usual manner. The tongue B, Fig.4, does not differ except at its forward end from ordinary tongues insnap-hooks;- and is pivoted or hinged to the body in the usual manner.The forward end is made with the lateral projections a and b, and withthe slot c between them. 'Ihe lateral projections extend nearly to theedge of the shield a, and the slot c is formed to receive the rib m.

Thus constructed, the rib prevents lateral motion of the tongue, and theshield a prevents the ring or link to which the hook is attached fromcoming in contact with the end of the tongue. If the ring is turned overand strikes the back part of the tongue and pulls upon it, one or theother of the projections comes upon the opposite side of the ring, andthe strain comes upon the tongue itself, having no tendency to free thering from the hook.

I claim as my invention- A snaphook consisting of the body A, having theshield a and rib :u on its end, in combination with the tongue B, havingthe projections a b and slot c, substantially as shown and described.
